Sarcelles' urban green spaces and the Crould River corridor feature plane, oak, and linden as the main tree pollen sources, with exposure varying between these areas and the densely built suburban landscape. As part of the greater Paris metropolitan area, the Val-d'Oise agricultural landscape contributes substantial grass and crop pollen, while local sources dominate and surrounding Île-de-France farmland adds additional exposure.

Hazel and alder open from January before birch and plane peak through April and May, with grass peaking through June and July. The urban heat island extends the season slightly, while surrounding farmland extends exposure and the dry regional climate means fewer interruptions.
How often is the Sarcelles pollen forecast updated?

Does pollen in Sarcelles come from nearby or far away?

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Are pollen levels in Sarcelles based on measurements or forecasts?

Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.

Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Sarcelles, modern forecasts combine recent measurements, weather data, and information about local vegetation.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
